Little Swan washing machine, the motor rotates intermittently, and the paddle wheel does not rotate.
Fault analysis: According to the fault phenomenon analysis, there may be a fault in the mechanical system or a fault in the electrical system. First check that the output voltage of the program controller is normal, which indicates that the program controller is working well. Then check the washing button switch. If its spring sheet is elastic or deformed, the contact point has poor contact, the wire welding head is poorly welded, de-soldered, or disconnected, it may cause the fault of the paddle wheel not rotating. Upon inspection, it was found that the washing button switch had poor contact. After cleaning and repairing, it was still ineffective. Replace the washing button switch, start the machine for testing, the motor runs normally, but the paddle wheel still does not rotate. Therefore, it is judged that there is a fault in the mechanical system of the washing machine.
Fault inspection: Remove the rear cover of the washing machine. Upon inspection, it was found that the V-belt fell off. The reason for the V-belt falling off is that the clutch pulley is twisted and deformed, causing the symmetrical planes of the two pulley grooves not to be on the same plane, so that the V-belt vibrates during operation and falls off. After replacing the clutch pulley, start the machine for testing, the washing machine works normally, and the fault is eliminated.
